A Remarkable Engine. j,

From the Aeic York Evening Post
A report comes from Cincinnati in regard
to new steam engine that has been at
tracing considerable attention there, and
which is said to practically obviete all waste
of steam. 1t was invented by Cincinnati
man, and the drawing was exhibited In the
Chamber of Commerce in that city. 1t Is
said that the drawing will also be shown on
the Stock Exchange in this city, and that
company has been formed with capital OF
$500 900, and preparations already made to
construct marine engine of 5000 horse
power The inventor claims that the sub
ject has been looked into and reported upon
faYorably by number of experts.
The engine consists of four single-act1ng
cylinders Of equal dimensions placed at the
corners Of a square, one pair above the
other, leaving space between them for the
main or crank shaft The position OF tine
hy-wheel is in the centre OF the frame
work, running between the cylinders. This
position is Just the reverse of the balance
wheel in all other engines. and it is so placed
In order to secure an equal balance. The
pistons of the cylinders are connected with
the main shaft in such way that the piston
of the top cylinder on one side works IN
conjunction with the piston Of the cylinder
underneath on the same side. They are
automatically connected, and are released
as the in and out strokes are made. The
other pair of cylinders are connected in the
same way and may be said to work in
ouples
= Steam is admitted to the couple on one
side, and the pistons are driven to the end
OF their stroke, one to the right and the
other to the left The crank with which
this couple is connected is then at the dead
centre. At this point, by peculiar mechan
ism. the pistons are connected and balanced
i'll such a manner that the pressure of steam
in one cylinder is against that i'll the other,
so that to all intentS and purposes it is
single piston-head with equal pressure of
steam on each side The piston heads are in
a state of equilibrium, and remain so until
by the action of the other pair they are re-
stored to their original position as at the be-
ginning of the stroke. At this instant they
are automatically relieved of their equilib-
rum, and are left free to be driven forward
again by pressure, while the balancing
movement Is as instantaneously transferred
to the opposite set of pistons.
1t is claimed for this engine that its con-
struction is such that there will be no launch
ing backward or forward as in other
engines, by the plunging OF a single piston;
as two of its pistOnS are going out in oppo-
site directions, right and left, and two are
returning from the right and left, perfectly
balanced, and with a steady motion insured
by the hywheel. A further claim is made
that the same sized engine of this type, in
diameter of cylinder and length OF stroke,
will develop from 33 to 80 per cent more
power, and save not less than IS per cent.
in fuel, by reducing the boiler capacity
necessary about threefourths, than the
most improved type of engine. There are
no valves, eccentrics, steam-chests, cut-offs,
link motions, etc, to get out of order, and
piston speed of from 600 to 800 can be at
tanned with perfectly smooth movement.
Mr.. j. G.. Matlock says in regard to this
engine: "This is the most daring claim that
|, in my fifty years of mechanics, ever
heard or read of man making-that is. To
drive the steam back into the boiler instead
of exhausting it into the air or into con-
denser'-and though at first il looks like an
absurdity, as it appeared to me when first
saw it, after long study over it for nights
and days, | now believe that it can be done.
If this inventor accomplishes it he will make
old iron of all the steam engines in the
world"
Other prominent engineers expressed in
terest in the matter to-day, but declined to
express any opinion upon the subject until
they had made thorough examination
